AV:L/AC:H/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.7.9

Description The issue arises from the xen iret function in arch/x86/xen/xen-asm 32.S, which does not properly handle an invalid value in the DS segment register on 32-bit Xen paravirt ops platforms. This allows users in the guest operating system to gain privileges within the guest OS through a modified application.

Recommendations For Linux kernel versions prior to 3.7.9, update to version 3.7.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the xen iret function in the affected Linux kernel versions until a patch is available.
